23.Remove the CKP sensor connector bracket(A).
24.Remove the cylinder head assembly.
(1) Remove the bolts in 2~3 steps as following orders.
If the bolts are not removed as the order, the deformation of the head assembly can be occurred.
(2) Put the cylinder head assembly on a wooden block after removal from the cylinder block.
Ensure that the surface between the cylinder head and the block is not damaged.
REPLACEMENT

camshaft. Ensure that the pin will not be installed in the hole for oil feeding.
Tightening torque
66.7~78.5Nm(6.8~8.0kgf.m, 49.2~57.9lb - ft)
After tightening the CVVT bolts, rotate the CVVT assembly housing counterclockwise by hand to seat the lock
pin in the CVVT assembly in good position.
Fix the hexagonal part of the camshaft in a vice when tightening the CVVT bolts. Do not fix the CVVT housing
or sprocket in a vice.
4. Install the camshaft in the cylinder head assembly.
(1) Align the timing mark of the camshaft timinig chain.
LH camshaft chain timing mark
RH camshaft chain timing mark
Both timing marks should face upward in reassemby.
5. Install the timing chain tensioner.
(1) Insert the set pin by pressing the timing chain tensioner.
(2) Install the chain tensioner(A) in the cylinder head assembly.

6.Install the camshaft bearing caps.
Tightening torque
Bearing cap bolt(A: 6×38) - 10.8~12.7Nm(1.1~1.3kgf.m, 8.0~9.4lb- ft)
Bearing cap bolt(B: 8×38) - 20.6~22.5Nm(2.1~2.6kgf.m, 15.2~18.8lb - ft)
When installing the bearing caps, check the marks on them as shown below and install them in its proper
position.
A(LH/RH HEAD): L(LH), R(RH)
B(Intake/Exhaust): I(Intake), E(Exhaust)
C(Cap no.): 1,2,3
When installing the bearing caps, turn the crankshaft to place a piston in the middle of the block because
linterference between valves and pistons can occur.

(2)Connect the breather hose(B) from air cleaner hose.
(3) Connect the MAF connector(A).
26. Install the engine cover.
27. Refill engine coolant.
DISASSEMBLY
Identify MLA(Mechanical Lash Adjuster), valves and valve springs as they are removed so that each item can be
reinstalled in its original position.
1. Remove MLA(Mechanical Lash Adjuster)s(A).
2.Remove valves.
(1) Using SST(09222- 3K000, 09222 - 3C300), compress the valve spring and remove retainer lock.
(2)Remove the spring retainer.
(3) Remove the valve spring.
(4) Remove the valve.
Page 53 of 1575
(5)Using SST(09222- 29000), remove the valve stem seal.
Do not reuse the removed valve stem seals.
3. Remove OCV(Oil Control Valve)(A).
INSPECTION
CYLINDER HEAD
1. Inspect for flatness.
Using a precision straight edge and feeler gauge, measure the surface contacting cylinder block and the manifolds
for warpage.
Flatness of cylinder head gasket surface
Standard : 0.03mm(0.0012in.) or less
Flatness of manifold gasket surface
Standard : 0.15mm(0.0059in.) or less
2.Inspect for cracks.
Page 54 of 1575
Check the combustion chamber, intake ports, exhaust ports and cylinder block surface for cracks. If cracked,
replace the cylinder head.
VALVE AND VALVE SPRING
1.Inspect valve stems and valve guides.
(1) Using a caliper gauge, measure the inside diameter of the valve guide.
Valve guide inside diameter
Intake / Exhaust : 6.000 ~ 6.015mm (2.2362 ~ 2.2368in.)
(2)Using a micrometer, measure the outer diameter of the valve stem.
Valve stem outer diameter
Intake : 5.585 ~ 5.980mm (0.2348 ~ 0.2354in.)
Exhaust : 5.950 ~ 5.595mm (0.2343 ~ 0.2348in.)
(3)Calculate the clearance between the valve guides and the stems by difference between the valve stem
measured diameter and the valve guide measured inside diameter.
Valve stem - to- guide clearance
[Standard]
Intake : 0.020 ~ 0.050mm (0.0008 ~ 0.0020in.)
Exhaust : 0.035 ~ 0.065mm (0.0014 ~ 0.0026in.)
[Limit]
Intake : 0.10mm (0.0039in.) or less
Exhaust : 0.13mm (0.0051in.) or less
2. Inspect valves.
(1) Check the valve face angle.
(2) Check that the surface of the valve for wear.
If the valve face is worn, replace the valve.
(3) Check the valve head margin thickness.
Page 58 of 1575
If the end play is greater than the maximum, replace the camshaft. If necessary, replace the cylinder head.
(3) Remove the camshafts.
CVVT ASSEMBLY
1.Inspect CVVT assembly.
(1) Fix the CVVT assembly with a vice. Ensure that the cam lobe and journal is not damaged.
(2) Check that the CVVT assembly will not turn.
It should not be turned.
(3) Apply vinyl tape to the retard hole except the one(A) indicated by the arrow in the illustration.
(4)Wind tape around the tip of the air gun and apply air of approx. 150kpa(1.5kgf/cm², 21psi) to the port of the
camshaft.
(Perform this in order to release the lock pin for the maximum delay angle locking.)
When the oil splashes, wipe it off with a shop rag.
(5) After the lock pin released, the CVVT assembly can turned in advanced direction.
If the air applied is leaked much, the lock pin can not be released.
(6) Except the position where the lock pin meets at the maximum delay angle, let the CVVT assembly turn back
and forth and check the movable range and that there is no resistance to movement.
Standard: Movable smoothly in the range about 60°
(7) Turn the CVVT assembly with your hand in retard direction and lock it at the maximum delay angle position.

REASSEMBLY
a.Thoroughly clean all parts to be assembled.
b. Before installing the parts, apply fresh engine oil to all sliding and rotating surfaces.
c. Replace oil seals with new ones.
1. Install valves.
(1) Using SST(09222- 22001), push in a new valve stem seal with applying engine oil.
a.Do not reuse old valve stem seals.
Incorrect installation of the seal could result in oil leakage past the valve guides.
b. Reassemble the valve stem seals
(2) After applying engine oil on the outer surface of each valve stem, insert the valve in the valve guide.
Install the valve, valve spring and spring retainer.
When installing valve springs, the side coated with enamel should face toward the valve spring retainer
(3) Using the SST(09222 - 3K000, 09222 - 3C300), compress the springs and install the retainer locks. After
installing the valves, ensure that the retainer locks are correctly in place before releasing the valve spring
compressor.
Page 60 of 1575
(4)Lightly tap the end of each valve stem two or three times with the wooden handle of a hammer to ensure
proper seating of the valve and retainer lock.
2. Install MLAs with engine oil applied on its surface.
Check that the MLA rotates smoothly by hand.
MLA should be reinstalled in its original position.
3. Install OCV(Oil Control Valve)(A).
Tightening torque
7.8 ~ 9.8Nm(0.8 ~ 1.0kgf.m, 5.8 ~ 7.2lb - ft)
a.To install OCV with gray colored connector into RH bank.
b. To install OCV with black colored connector into LH bank.
